SILAS E. BAILOR, OF TARKIO, MISSOURL' DRAFT-EQUALIZER FOR CULTIVATORS.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed February 6. 1907. Serial No 356.053.

To all whom it may concern:

Be'it known that I, SILAS E. BAILOR, a citizen of the United States, residing at Tarkio, in the county of Atohison and State of Missouri, have invented a new and useful Draft- Equalizer for Cultivators, of which the following is a specification.

The invention relates to improvements in draft equalizers for cultivators.

The object of the present invention is to improve the construction of draft equalizers, and to enable the same to be readily mounted on a cultivator, having laterally adjustable arches, and to provide a draft equalizer adapted to exert a downward pressure on the cultivating devices for holding the same in the soil.

Another object of the invention is to provide a draft equalizer adapted to permit a limited lateral oscillatory movement of the means for connecting the whififletrees with the equalizing levers.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a front elevation of a draft equalizer, constructed in accordance with this invention and shown applied to a cultivator. Fig. 2 is a vertical sectional view, taken substantially on the line 22 of Fig. 1. Fig. 3 is a detail view, illustrating the manner of mounting the guide pulleys or sheaves. Fig. 4 is a detail sectional view, taken substantially on the line 4-4 of Fig. 3.

Like numerals of reference designate corresponding parts in all the figures of the drawing. p

11 designate a pair of vertically swinging equalizing levers, which are fulcrumed at an intermediate point by bolts 2 on arches 2 of a cultivator, and which are disposed transversely thereof at the front portion of the same. The frame of the cultivator is provided with a front transverse bar or member 3 preferably constructed of channeled iron, and having a groove or channel at its rear face to form a way for the slidable arches 2 The slidable arches are composed of vertical sides and connecting top portions, and they are provided at the upper ends of their sides with suitable means for slidably connecting them with the transverse baror member 3 The bolts 2 pierce the equalizing levers and the transverse connecting top ortions of the arches, and are supported by Inclined braces 4 extending upwardly and inwardly from the outer sides of the arches to the pivot bolts, as clearly illustrated in Fig. 1 of the drawing.

The inner arms of the equalizing levers are twice the length of the outer arms, and both the inner and outer arms of the levers are connected by inner and outer links or rods 3 and 4 with inner and outer chains 5 and 6, or

other suitable flexible connections, which@ pass beneath inner and outer grooves or guide pulleys 7 and 8. The outer flexible connections 6 are directly connected to the outer swingletrees 9, and the inner flexible connections are secured to the ends of a transverse connecting bar 10, to which the central swingletree 11 is centrally connected by a suitable coupling 12.

The inner and outer pulleys or sheaves 5 and 6 are mounted in upwardly extending brackets 13 of pivoted members 14, which are connected with the plow beam 15 in rear of the pivotal points thereof, and which extend in advance of the pivotal points, whereby the plow beams and the pivoted members constitute levers, through which the equal-. izing device is adapted to force the cultivating devices into the ground, when the cultivator is in use. The brackets 13 are composed of vertical sides and a connecting bottom portion, and the front ends of the pivot members are secured to the upper faces of the connecting bottom portions of the brackets by bolts 16, or other suitable fastening devices, but the brackets may be formed integral with the pivot members, if preferred.

The plowbeams 15, which are mounted on c laterally extending pivots 17 of the'arches 2 have spacedlongitudinal bars or members 19 and-20, which are bolted, or otherwise secured to shanks or bars-21 of-bearings 22 through which the pivots 17 pass. The bearings 22 are adjustably mounted on the pivots 17 by collars 28 and set screws 24, and the shank or bar 21, which is interposed between the bars or members 19 and 20 of the plow. beams, are providedat intermediate points with laterally extending ears 25, lo-

cated above and below the contiguous bar or member 20 and receiving an upwardly extending pivot 26. The pivots 26, which are formed integral with the oscillatory memhere 14, are secured in the openings of the ears 25 by means of keys 27, or other suitable fastening devices. The ivoted mem bers 14 are adapted to swing laterally of the cultivator, and they thereby enable the cultivator to be drawn with'greater case than heretofore.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is

1. In a draftequalizer for cultivators, the combination with a cultivator frame, and arches slidable thereon and movable'laterally of the cultivator frame, of transversely disposed equalizing levers fulcrumed on and carried by the arches, guiding means also carried by the arches and located at the bottoms thereof, whiffletrees, and flexible connections passing through the guiding means and connected with the whiffletrees and with the equalizing levers.

2. In a draft equalizer for cultivators, the combination'with a cultivator frame, and arches slidably mounted on the cultivator frame and -movable transversely thereof, said arches being composed of sides and top connecting portions, of transversely disposed equalizing levers provided with pivots mounted on the to connecting portions of the arches and carried by the latter, inclined braces extending from the pivots tothe outer sides of the arches, guiding means also carriedby the lower ends of the sides of the same, whiflletrees, and flexible connections passed through the guiding means and connected with thewhiffletrees and with the levers.

3. In a draft equalizer for cultivators, the combination with a frame, and plow beams, of pivotally mounted laterally movable members, guiding means carried by the members, flexible-connections operating in the guiding means, equalizing levers connected with the flexible connections, and whiffletrees also connected with the flexible connections.
